OEM Trac Lok for an '84 and up 9.25 and a Mopar master install kit. These are both new, uninstalled but not in the original box. My buddy bought the LSD than sold his truck before installing it. The install kit was thrown in with some gears I bought but I don't need the kit. Install kit includes a tube of Mopar RTV and Mopar friction modifier for the LSD. Looking for $300 for both. That includes UPS ground shipping in the 48 states. I prefer Paypal for payment.
